An approximate formula is derived for Bethe-Bloch equation for the energy loss of electrons.The formula is useful for electrons with energies smaller than 300 KeV and gives an approximate range-energy formula of the type R=aEn. This formula is compared with the empirical range-energy formulas obtained by many authors. Also, some simple approximate formulas are obtained for the relation of “rate of energy loss-path length” and for that of “energy-path length”.
